The Quidditch Cup:Gryffindor's or Slytherins?

This year... One team...

One chance of victory.

Why, its the Hogwarts Quidditch Finals! If you don't know(and why the hell would you not know?)

The official rules of Quidditch are partially described in Quidditch Through the Ages. They are said to have been laid down in 1750 by the Department of Magical Games and Sports. Some of the more common rules are as follows:

• Players must not stray over the boundary lines of the pitch, although they may fly as high as desired. The Quaffle must be surrendered to the opposition if any player leaves the boundary. Quidditch matches in the Harry Potter films, however, show players often deliberately flying over the boundary lines and even around the spectator towers. This is possibly because these are just school matches and thus are not as strict regarding the rules.
• Time out may be called at any time by a team Captain. It may be extended to two hours if a game has already lasted for more than twelve hours. Failure to return to the pitch afterward disqualifies the offending team.
• The referee can impose penalties if a foul occurs. A single Chaser from the fouled team takes a penalty shot by flying from the central circle towards the scoring area. The opposing team's Keeper may attempt to block this shot, but no other player may interfere.
• Contact is allowed, but a player may not grasp another's broomstick or any part of his or her body. (Draco Malfoy breaks this rule in Prisoner of Azkaban by grabbing Harry's broomtail to stop him from seizing the Snitch.)
• No substitution of a player is allowed, even if one is too badly hurt to continue (rare exceptions may be made when the game continues for a great length of time, and players become too fatigued to continue).
• Players may take their wands onto the pitch, but they must not be used on or against any players, any players' broomsticks, the referee, any of the four balls, or the spectators. (The right to carry wands at all times was granted during the height of wizard and witch persecution by Muggles, according to Quidditch Through the Ages).
